Electricity Saving Tips For Homes And Offices

Split or Window which air conditioner should you buy?

By on May 1, 2017

Should I buy a split air conditioner or a window air conditioner? This is a question that many air conditioner buyers thinks of, before making a purchase. And we keep getting this question quite regularly at Bijli Bachao. It is not just about split or window, but about a whole lot of things that should be considered while buying an air conditioner.  Air Conditioner is an appliance that can significantly blow up your electricity bills and utmost care should be taken while buying one. With this article we would try to provide you some guidelines on things to take care of before making a purchase decision for an air conditioner. Please note an air conditioner bought once will go on for next 10 years at least and thus it is important to make a right decision.


Split vs Window

Buying a split or a window is something that worries a lot of people. But from energy efficiency perspective there is no preferred choice. Both split and window can be equally efficient. What matters is EER or Energy Efficiency Ratio of the air conditioner. EER represents the amount of cooling an air conditioner can provide per watt of electricity it consumes. Bureau of Energy Efficiency rates air conditioners on its star rating based on EER of air conditioners. Higher the EER of air conditioner higher the star rating it will have. So a 5 star rated air conditioner provides more cooling per watt of electricity used.

Both split and window can have high EER ratios. But it is observed that Split air conditioners have more number of models in BEE 5 star rating as compared to Window air conditioners (check our research on air conditioners at this link: link). So if you are looking for high efficiency air conditioners then split air conditioners can provide you more options.

The main difference between the two is that window air conditioner has a single unit whereas split air conditioner has 2 units (indoor and outdoor). Split is lot more silent in operation as compared to window and looks aesthetically pleasing, but is relatively more complicated to install and requires more space as compared to window air conditioner.

Right sizing an air conditioner is very important

The most important thing that one should figure out before buying any air conditioner is the right size of the air conditioner. This can significantly impact your electricity bills. And from size we mean tonnage of air conditioner. Every room that is cooled has a certain amount of heat that depends on:

  1. Size of the room. This determines the amount of air in the room that needs to be cooled.
  2. Number of people in the room. Every human being emits heat and air conditioner needs to cool it.
  3. Amount of stuff kept in the room. Please note every item kept in the room will get cooled from the air conditioner, so lesser the stuff, lesser the electricity air conditioner will consume.
  4. Number of electrical appliances in the room (most electrical appliances emit heat, especially lights). Incandescent light bulbs can increase cooling load.
  5. Windows in the room. More the windows, more is the heat coming from outside. Well-insulated windows reduce cooling load. Check our insulation section for more details: https://www.bijlibachao.com/Save-Electricity/Insulation/
  6. Walls facing the sun can increase cooling load. Touch your walls and windows to check if they are hot or not and using the tips in insulation section to prevent heating of the room.

The amount of heat in a room and that coming in from walls and windows is represented in BTU (or British Thermal Unit). BTU is sum of heat from all the above-mentioned sources.

Every air conditioner has a cooling capacity, which is represented in BTU/hr. It is the BTUs of heat that it can remove in an hour. If the heat coming in the room (in BTUs) is more than the heat that air conditioner can remove, then the air conditioner will not be as effective. Thus an undersized air conditioner cannot remove heat effectively and the compressor of the air conditioner will continue running all the time thereby consuming more electricity.

With an undersized air conditioner, the compressor will keep running all the time and the temperature will not reach the desired level. They will not only be ineffective in cooling, but will also consume more electricity.

An oversized air conditioner will not only over cool your room but also will be ineffective in removing the humidity in a room. So if you set AC to 25, the extra energy that the compressor provides will cool it beyond 25. It will have shorter run cycles but all air conditioners are designed for optimum run cycles and if the cycle is shorter than that then the efficiency is reduced (source: energy star).

So every air conditioner is designed to run at optimum efficiency only if it is used as per the right size. So always size the air conditioner properly. You can use the calculator available at this link before buying an air conditioner: http://www.lg.com/in/support/ac-tonnage-calculator.

If you are not sure about what size to buy, you can always buy an inverter technology air conditioner, as it adjusts to the size and requirements of the room automatically, and thus makes optimum electricity consumption. To check more about inverter ac see our article: Air Conditioners with Inverter technology can help save electricity.

Look for the right options in the air conditioner

In a previous article (Various modes for running air conditioners and their impact on electricity bill) we discussed about various modes of air conditioners and their impact on electricity consumption. It is very important to figure out if the air conditioner has all the modes as per your requirement. If you live in humid area, a dry mode is important. Any air conditioner with energy saver mode and features should be preferred.

Star rating is for real

BEE Star rating of air conditioner does matter a lot. Any air conditioner would consume anywhere between 1-2 units per hour of usage based on tonnage, efficiency and size. Which means if it is used for 10 hours per day, it can consume about 10-20 units in a day or 300-600 units a month (for 10 hours of use daily). At an average rate of Rs 6-7 per unit (you can check your per unit rate using our calculator: Online Electricity Bill Calculator – For all states in India) it can be close to Rs 1800-4000 per month. If your usage is high then the yearly cost of an air conditioner can go very high. In case of high usage, incremental cost of buying a higher star rated air conditioner can easily be recovered in a few years. Please note that the air conditioner will work for at least 10 years and the electricity prices are on a rise. Buying an efficient one while buying a new air conditioner can prevent a lot of heartburn for you in future.

It is important to make a right decision while buying an air conditioner, as it is a long-term utility for you. Do not let lucrative deals, discounts and persuasion by a sales person impact your decision to buy an efficient appliance. A wrong decision on an appliance like air conditioner can significantly impact your electricity bills. We are trying to work out a calculator that can help you choose the right air conditioner for you and hope to release it soon. Till that time you can check the list of top ten most efficient air conditioners at: Top Ten Air Conditioners in India by electricity consumption and size.

My window AC compressor never stops even if runs on 24degree as it also cools very good &it also doesn't drips water from outside as long as it runs but after it stops it drips water from outside it's drainage hole provided

2
Abhishek Jain (Mod)

Get the drainage of the AC checked. Usually the water drips when the AC is running.

3

Which ac to buy in between 1.5ton ogeneral window AC or other brand 1.5 ton split ac

4
Abhishek Jain (Mod)

I would not suggest to buy any Window AC because they are not energy efficienct ... they will consume a lot of electricity .... to check list of split ACs, check this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Hi Savita,

You may buy the most fuel efficient car in the market, but if the daily usage is only 2-3 kms, you will never be able to get an ROI on it. Similarly you buy buy the most energy efficient 5 star inverter AC, but then you will not get an ROI unless the usage is good enough and your electricity costs are appropriate to provide ROI on the AC. I would suggest that you use the calculator given on the link that you have mentioned. It takes in a lot of parameters like you city, room dimensions, room location and your regular usage and based on the climate of the city, electricity tariffs in the city, etc it suggests the right tonnage as well as cost of operating various star rated ACs.

All I can say is that if your usage is not exceptionally high (about 2500+ hrs a year), then 5 star inverter AC will not have an ROI (if that is what you mean from economic). For regular home use (about 1000-1500 hrs a year), BEE 3 star inverter ACs are decently economic currently. An if you want the most Value for money product then I think LG BEE 3 star inverter AC models with copper condenser are great value for money. Even their Aluminium models are quite good if your area is not highly corrosive. You may check any of these:

LG JS-Q12BTXD (Flipkart Link: http://fkrt.it/6CXjB!NNNN )
LG JS-Q12BPXA (Flipkart Link: http://fkrt.it/oSPr~TuuuN , Amazon Link: http://amzn.to/2s2WNq8)
LG JS-Q12AFXD (Amazon Link: http://amzn.to/2s2BXHM )
LG JS-Q12CPXD (Amazon Link: http://amzn.to/2t35uQz )
LG JS-Q12AUXA (this is a copper model).

Suggest to buy one ton air conditioner of which brand /company

10

Hi,
I'm planning to buy a new ac this year. We already have one ac - voltas bought 3 yrs back and the after sales service is very very poor in Kolkata. This time around we are looking forward to a company with good after sales service. Could you please suggest some? We will buy a 1 or 1.2 tonne split ac..budget ~30 K.
Thanks in advance!

11
Abhishek Jain (Mod)

Hi Aritra,

Which brands are you looking for? We do not have location specific data on service levels of various brands. If you can tell me the brands that you are looking at, then I can suggest some models. By the way only Voltas and Hitachi have 1.2 ton ACs. Else you will have to go for 1 ton.

12

I move a lot like every 3 year or so, should i go for split ac.? because I feel thats more efficient and has advantages over window AC.

13

Window ac cools much faster than split. Also repeated dismantling of split ac for shifting will reduce cooling efficiency. Moreover, split ac cools nicely for about a year or two, but after that as the indoor blower gets dirty, cooling efficiency will reduce drastically and cleaning the blower properly without dismantling is not possible, and each time the ac is dismantled, it has to vacuumed and gas topped.

14
Abhishek Jain (Mod)

The only problem with Window ACs is that you will not find too many good options in it. Manufacturers are slowly reducing their window AC catalogue. And in window ACs there are very few energy efficient options. So the electricity bills will also be high if your usage of AC is high.

15
Jaydeep shukla

I want to buy AC.for 13 x 10 x 10 room size.in Vadodara,my uses in summer in night.please suggest best brand and toneg,also 3 star non inverter or 3 star inverter.

16
Abhishek Jain (Mod)

Hi Jaydeep,

3 star non inverter is no comparison with 3 star inverter. In fact 3 star inverter is something that is comparable with 5 star non inverter. So 3 star inverter would be my suggestion. I have replied to your previous question and have some additional questions. Once I get answers to those, I can make some suggestions.

17
Jaydeep shukla

Hitachi, blue star,lg

19
Abhishek Jain (Mod)

Hi Govind,

You would need 1.5 ton Air Conditioner for the room. I doubt that you can get Hitachi inverter AC in your budget. But in Voltas you can get BEE 3 star rated inverter ACs. You can check these:

Voltas 183V IY (Amazon Link: http://amzn.to/2r0yhnK )
Voltas 183V EY (Flipkrt Link: http://fkrt.it/!TGqh!NNNN )
Or Voltas 183V DYb

The best copper inverter AC you can get in your budget are from LG:

LG JS-Q18SUXD (Amazon Link: http://amzn.to/2oMG2Le )
LG JS-Q18AUXA (Amazon Link: http://amzn.to/2oMjWqB )

The SU, AU and TU series in LG have copper.

If you want non inverter then you can check these:

Hitachi RAU518KWD (Amazon Link: http://amzn.to/2rt726v Flipkart Link: http://fkrt.it/!Tc8v!NNNN )
Voltas 185 PY

Hitachi model would be better.

20

Very important information, thanks for sharing.

21

Hi sir
my name is pradeep planning to buy a A.C first time . My room size is 10*9. So i am just confuse which A.C I should buy either split AC or Window Ac. I have window also in my room. So please suggest me sir which one I should buy and also the power consumption ?

22
Abhishek Jain (Mod)

Hi Pradeep,

It will depend on the tonnage that you need for your room. And tonnage requirements depend on room size, city (Delhi is super hot and needs more cooling and Mumbai is not that hot), room location (if you are on top floor your room becomes a furnace, else it is cooler) ….. so it depends on multiple things. I would suggest that you first calculate the tonnage that you need for your room using the calculator on this page: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

The calculator also has tariffs built in and if you input your daily and annual usage then it will show you costs of buying different star rated ACs along with their electricity consumption. Once you decide on tonnage, star rating (Inverter/non inverter) and give me your budget, I can suggest you something.

Please note window ACs are outdated. They have old technology and their efficiency levels are 1 level lower (BEE 3 star window AC is equal to BEE 2 star rated Split AC). So in general we do not recommend going for window AC unless there is no option to fit split AC.

23

Which ac life is more window ac or split ac

24
Abhishek Jain (Mod)

Both are equally good.

25

Assume that all the other conditions remain the same - size of the room, cooling requirements etc. The air conditioner is proposed to be used for 10 months / year, 8 hours a day. Which is better - a 5 star non inverter split air conditioner or a 3 star inverter air conditioner? Essentially, we are comparing a 5 star non inverter vs a 3 star inverter air conditioner. Which will save more power?

26
Abhishek Jain (Mod)

Every star rating is a range of efficiency. Any Non inverter AC with EER above 3.5 is BEE 5 star rated. There are ACs with EER of 3.9 as well. Based on data, BEE 3 star rated inverter ACs start from ISEER of 3.55. But they go as high as 4.

Now a lot depends on which model you are comparing. If the choice is between BEE 5 star non inverter AC of 3.51 and Inverter AC of ISEER 4, then the inverter model wins hands down.

If the comparison is between non inverter AC of 3.9 and Inverter AC of ISEER 3.55, then the comparison becomes a bit tricky.

It becomes tricky because, the numbers are calculated in standard conditions, where the room's requirement is fixed (1 ton or 1.5 ton). But if your room needs 1.2 ton and you put a 1.5 ton inverter AC, then inverter AC would win hands down because at lower capacity, inverter ACs give better efficiency. Also if your room needs 1.2 ton and you put a 1 ton, then Fixed Speed AC would be better as inverter ACs run at lower efficiency at higher capacity.

27

Thanks Abhishek for your response.

1) Does this mean, the best way to save money is to buy an inverter AC which is has slightly more capacity that what is required for your room size (surplus capacity) so that it runs more efficiently? Is that the magic mantra to save power?

2) Do all AC's carry BEE and ISEER ratings simultaneously? In your anawer you have made reference to both ratings. How do these 2 ratings "interact" with each other? How are they related?

28
Abhishek Jain (Mod)

Here is my response:

1) You either buy the right sized one with good ISEER or oversized one. Basically the approach that I follow is to try to get the best (with high ISEER) in one's budget. Be it right sized or oversized.

2) BEE is Bureau or Energy Efficiency a govt of India organization that assigns star ratings to Air Conditioners. It gives star rating from 1 to 5. Each star rating is provided to ACs that lie in a range of ISEER (Or Indian Seasonal Energy Efficiency Ratio). All manufacturers have to get their models tested in a lab to get ISEER value for their AC. This is then submitted to BEE to get star rating. You can learn more on this page: https://www.bijlibachao.com/air-conditioners/iseer-star-labeling-inverter-air-conditioners-india.html (this page has range of ISEER currently valid for different star ratings given by BEE).

29

Dear Abhishek

Does this mean all air conditioners have an ISEER rating? What is the threshold (minimum) value of ISEER above which it is considered to be a power saving / efficient machine?

Thanks,

Mohan

30
Abhishek Jain (Mod)

All ACs should have ISEER rating. Currently BEE star rating is not mandatory for Inverter ACs. Although most brands have got their models BEE star rated, but still some brands do not have BEE star rating.

BEE sets a minimum performance standard that is allowed to be sold in India. And the minimum standard is given BEE 1 star. There is no other level to say anything is power saving or efficient. One has to choose star rating or efficiency level depending on his/her own usage. If your usage is less then you can go for any model. If your usage is high, you have to choose a model accordingly.

31

Hi Abhishek,
I am based in Mumbai and looking for a window AC (rented apt) and for a room with 2 people - approx. 14*18 feet., two windows approx. 12 sq ft., middle floor.
I am keen on a 5 star rating AC, and good after sales service. O General I believe is too expensive, and I am keen on Voltas.
What recommendations would you make?

32
Abhishek Jain (Mod)

Hi Aiman,

You would need 1.5 tons cooling. There are hardly any energy efficient options in window ACs, so the only ones I would recommend are these:

Hitachi RAV518HUD (Amazon Link: http://amzn.to/2negUKO , Flipkart Link: http://fkrt.it/AF7GETuuuN )
Hitachi RAT518HUD (Amazon Link: http://amzn.to/2mMYF3P , Flipkart Link: http://fkrt.it/AFS7ETuuuN )

33

my room size is 12x10 and will be shared by 2 persons and budget is below 40k and i stay in hyderabad, we use moderately..... so what are the best brands and models in inverter ac

34
Abhishek Jain (Mod)

Hi Prithvi,

You can get the list of top brands and top models on this page: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

I guess your budget is including installation. In that case you can look at these models:

Blue Star 3CNHW12TAFU
Blue Star 3CNHW12CAFU (Amazon Link; http://amzn.to/2nEbaM9 )
LG JS-Q12PWXA
Daikin FTKH35 (Flipkart Link: http://fkrt.it/2t9De!NNNN )
Voltas 123V EY (Flipkart Link: http://fkrt.it/Lh9eITuuuN )
Daikin FTKH35

35

Does split Air Conditioners are prone to have functional problems if they are reinstalled to a new room/location? This concern is due to fact that I have transferable job.

36
Abhishek Jain (Mod)

If removed and installed properly by an experienced technician, there should be no problems with the same.

37

Sir please tell me which model I need to buy, 1.5 ton, split AC 5 star or 3star inverter AC. My budget is 35000 to 40000. Tell me both type models

38
Abhishek Jain (Mod)

Hi Srihari,

I do not think you will get a 1.5 ton BEE 5 star rated inverter AC in your budget. But you will surely get BEE 3 star rated inverter AC in your budget. Mostly models from LG, Samsung, Voltas or Whirlpool would be good in your budget.

You can look at these models:

In LG:
JS-Q18BTXD (Flipkart Link: http://fkrt.it/Iz6s~!NNNN )
JS-Q18NRXA (Flipkart Link: http://fkrt.it/IHuF6!NNNN )
JS-Q18BPXA (Flipkart Link: http://fkrt.it/IHj14!NNNN )

In Samsung:
AR18MV3HLWK (Flipkart Link: http://fkrt.it/IHRC5!NNNN , Amazon Link: http://amzn.to/2mLJmoL )

In Voltas:
183V EY (Flipkart Link: http://fkrt.it/U77~qTuuuN )
183V IY (Amazon Link: http://amzn.to/2ncHQyP )

between carrier superia 3 star and blue star v series 3 star............which one is good?
which one has better cooling capacity and air flow rate and also good specs wise in each segment?

40
Abhishek Jain (Mod)

Carrier Superia 3 star would be better in terms of cooling capacity as well as energy efficiency.

41

and what about the carrier octra 3 star? is this same in specs as the superia one?

42
Abhishek Jain (Mod)

Quite similar models, and the only difference is in the filters. Technical specifications are the same.

43

kindly throw some suggestions on floor standing ACs, which are portable option for people like me with transferable jobs.

44
Abhishek Jain (Mod)

Firstly, there are very few options available in floor standing ACs. Secondly, as they are not rated by BEE, it is difficult to guarantee the energy efficiency of the ACs. I am not sure how will they impact your electricity bills. It is better to avoid them for now.

45

Hello, I am looking to buy a split ac for my room of 10x10, We have a running runnel in front of our house because of which a dozen of WINDOWS AC's don't work more than 2 years. Becuase of some carbon problem, Please suggest me which company's AC I should go for? And what should be the capacity? That will work for long duration. :)

48
Abhishek Jain (Mod)

You should go for a brand that has all copper AC with strong corrosion protection. You can look at ACs from Hitachi, Daikin, Mitsubishi Heavy, Carrier. These brands have all copper ACs. In other brands some models are copper and some have aluminium condenser. You have to check the model.

Also there are lot of parameters that determine right size and right star rating for an AC. It will not be productive if I ask you all of them and then you reply and then I reply.

I am facing a weird problem for installation of split AC outdoor unit .The room in which Ac has to installed has one side a share wall between us and our neighbors.The other wall which faces outside has whole woden work with cupboards not a inch gap is left to drill the hole.Third side of the wall faces to attached bathroom which does not have enough ventilation.Now the fourth side of the wall which has common bath room the other side has enough ventilation which has both exhaust fan and Big ventilation window .Now the question is can i install my outdoor unit in my bathroom which we used it rarely.

50
Abhishek Jain (Mod)

You should install outdoor unit at a place that has good ventilation. Outdoor unit needs enough space and ventilation to throw out hot air.

51

I live in Ajmer, Rajasthan. I need to buy ACs at reasonable cost for two rooms. My house has only ground floor, roof is directly exposed to sun. AC will be used 4-5 months in summer. Temperature moves around 40℃.
~One room size is 13×11with two windows (6×5 both). 3-4 persons will be sharing the room. From which one window is directly exposed to sun in morning.
~second room is closed room with no direct sunlight exposure. Size is 11×10. Two person will share this room.
Can you please suggest me wh7ich AC should we buy? What is the difference between window AC and split AC?

~One room size is 13×11with two windows (6×5 both). 3-4 persons will be sharing the room. From which one window is directly exposed to sun in morning.

~second room is closed room with no direct sunlight exposure. Size is 11×10. Two person will share this room.

Can you please suggest me wh7ich AC should we buy? What is the difference between window AC and split AC?

Thanks Team Bijli Bachao for useful info.
i have 2 questions and it would be great, if you can guide

1. i have voltas 1.5 ton, 5 star split ac (3 years old), every year, i need to fill the gas, as it gets lost. Mechanic said - i need to change coil as it has aluminium coil which cant be repaired. Is it so?, if yes, would you advise me to go for copper coil this time.
2. i want to buy another 1.5 ton ac.Confused between split or window. Usage will be for 5-6 months that too at night only. (for Kids Bedroom). Presently at Kolkata and i keep on moving every 3 years. Mumbai might be next place.

57
Abhishek Jain (Mod)

Here is my response:

1) Aluminium coils do have this problem and it is better to go for copper. Copper is easier to repair. But all in all, it is better to have better corrosion protection for the condenser.

2) If you want to go for window AC then go for BEE 5 AC. Hitachi Summer QC model is as efficient as any BEE 5 star rated Split AC.

58

Bullcrepe article, doesn't say shoot about the differences between the two.

59

Hi Bijali Bachavo Team.
I will be moving frequently, say every 3to 4yr,
I feel window AC is better, 1.5 ton. I will be requiring AC for almost 12 to 18 hrs a day.

I am presently leaving in Rajasthan, I request you to suggest which company is better, keeping the provision of service also.

Thanks for the post

60
Abhishek Jain (Mod)

Hello Mr Prasad,

Window AC would be better for movement, also light on purse while buying, but looking at your usage, it would be heavy on your electricity bills. I would suggest going for inverter technology split AC for that usage.

61

Thanks Mr Abdi shekels Jain,

Which brand do you suggest?
I'm planning for Voltas 1.5 ton,
Or Bluestar.

62
Abhishek Jain (Mod)

Both Voltas and Blue Star are good. A lot depends on the model that you go for. Just like while buying a car, you may ask which brand is good Hyundai or Toyota .... but actually you have to look at whether you are buying Hyundai i10 or you are buying Toyota Camary .... there is a lot of difference .... so you have to look at model, not just the brand.

63

1st of all, thanking for sucha an useful information and research!! Appreciate this.

Hi,

I would suggest that you look at the calculator, list and FAQs on this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

It should help you choose the right size and model.

65

Dear team;

Pl suggest which ac is best for my room 13'×14' size ,sunlight come from the south side top floor pl suggest... Should I go for 1 ton or 1.5 ton...

66

Dear Team, Please guide me

I have finalized Two refrigerators based on the fuel consumption and capacity. Please guide me which one of the following two I have go for:

Samsung – Model RT47H567ESL/2015 &
Hitachi – R-V660PND3KX/2015

Regards,
Jayesh

67
Abhishek Jain (Mod)

Hello Mr Jayesh,

RT47H567ESL is BEE 4 star with annual electricity consumption of 296 units
R-V660PND3KX is BEE 4 star with annual electricity consumption of 339.

But RT47H567ESL is a 462 lts model while R-V660PND3KX is a 601 lts model. So two are quite different.

Respected Team Bijli Bachao,

I Am From Kolkata And My Room Size Is 11 By 11. I Have Installed A Panasonic 1 Tonn Split Air Conditioner 2 Months Back And Has Set The Temperature To 27 In Cool Mode And It Get Used For Around 12 to 16 Hours A Day.. My Electricity Bill Is Now Coming Somewhere Around Rs. 1500 Per Month. Is It Appropriate???

69

Sir for my 12' x 13' room at ground floor with only south side wall exposed to sunlight , is one ton inverter ac is sufficient , because at start it almost run on about 1400 watt (which is equal to 1.5 ton ac) then gradually going down to 1000 watt and more lower. please advice me. i am going for carrier superia 365 brand

70

sir i live in jalandhar punjab

71
Abhishek Jain (Mod)

For 12x13 room in Punjab, you would need a 1.5 ton inverter AC. A 1 ton inverter AC will not be sufficient. You can go for a Carrier Superia 1.5 ton inverter AC.

72
Abhishek Jain (Mod)

Hi Rashpal,
Which city do you live in? 12*13 room would require a 1.5 ton AC in most of the places. A 1 ton inverter can extend upto 1.2 tons max. 1400 watts is the power consumption of the AC, and not the cooling capacity. If you can tell us the city, we can tell the required amount of tonnage for your room.

73

Hi my name is Naresh planning to buy a A.C first time . My room size is 10*9. So i am just confuse which A.C I should buy either split AC or Window Ac. I have window also in my room. So please suggest me sir which one I should buy and also the power consumption ?

74
Abhishek Jain (Mod)

Hi Naresh,

If your main concern is electricity consumption then you will get better options in Split ACs. You can go through our video that explains more about window vs split: ..... all I would say is that manufacturers are slowly moving completely towards split ACs. However there are several factors that one need to consider while buying AC:

1) Tonnage of AC: Depends on several factors, but primarily on size of room, city where you live in, window sizes, people in the room. Oversized AC consumes more electricity, and undersized does not cool properly.

2) Star Rating: Choice of BEE 5 star/inverter tech or a lower rating depends on your usage of AC. If your usage is more than 1000 hrs per year (with tariff more than Rs 5), it is better to go for higher efficiency models. Benefit of inverter tech is that it is a variable tonnage AC and as the tonnage requirement is different every month and every day, this AC auto adjusts to the needs and thus saves electricity.

3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both. Once you have decided on star rating, the most efficient models from good brands can be selected.

If you provide us with more details as in which city you are in, what is the size of your room, which floor they are on, is there any floor above it, are the walls exposed to sun, usage in hours per day and months per year, and approximate budget, then we can suggest you something.

75

I stay in Secuderabad , and my house in ground floor and in my room has one window is there. And my room size is length-12'' and breadth 13''. Mostly I use in summer why because on summer it causes more heat in our room. So please suggest us a good AC either window or Split with power consumption as I am a normal family member.

76
Abhishek Jain (Mod)

Hi Naresh,
According to our calculation your room requires a cooling of about 1.4 tons. What is your budget for AC? And what is your usage of AC in hours/year?

The biggest point seems left out between Window and Split Ac is its maintenance especially of the Out door unit / Condenser Unit in a split which is prone to nuisance from birds & cats and even insects. The insulation widely used for insulating the copper tubes are of such inferior quality that within a few months of the first summer it is damaged. The insulation tube is required to be EPDM rubber which is strong and does not get affected by rain or shine.
If the tubes get heated up or damaged the very functioning of the split AC is badly affected leading to expensive repairs.
The installation is outsourced. 99.99% of these installation guys are most unreliable and unscrupulous. They use very cheap to cheap quality of copper tubes and insulation materials thus leading to lot of troubles in the medium run.

80

Hi Ramanatha,

I am staying in a rented accommodation and want to buy a AC.Could you please guide me which one is better window or split.

81
Abhishek Jain (Mod)

Thanks for the feedback Mr Ramanathan. Certainly a very important point. Installation is one big issue for split units. Installers are not well trained to install the ACs properly and that causes loss in efficiency.

82

Thanks for appreciating the points raised by me. It is noteworthy that the installers use substandard and low quality insulation material. The copper tubes used are often inferior quality. The thickness is dubious so much so they even get punctured easily even during installation. All these have a STRONG BEARING on the power consumption.

83

Can you please suggest which A/C is of low maintenance. I understand O'G or Daikin are good. Is it so?

84
Abhishek Jain (Mod)

Both General and Daikin are good. However rather than just brand, you should also look at model, its efficiency and features.

85

Yes true. I actually had a Voltas AC for last 4 years and had spent almost the AC cost on service/maintenance. So I am really looking for some ac which will stand good for few years, no/low maintenance cost.

Kindly advise the best 1.5 ton ac for Chennai all year hot weather.

my room size is 16 feet X 10.5 feet. Can I use 1.5 ton 5 star split Ac/window AC. Which is better

88
Abhishek Jain (Mod)

Hi Sanjay,
Which city do you live in? And is your room on the top floor with direct sunlight falling on the ceiling, or is it on a lower floor? We generally do not recommend people to go for window AC as there are very less efficient models in window ACs.
The choice whether you should go for split/window AC will depend upon your usage. What is your usage of AC in hrs/year?

89

I have a 220 sq foot room (13*17) just below the roof here in Kolkata. Temperatures soar around 37-38 degrees. Which AC would be ideal for me?

90
Abhishek Jain (Mod)

Hi Rajashi,

You should go for at least 2 ton AC for your room. An inverter tech AC would be good if your usage of AC is high as tariffs are quite high in Kolkata.

91

Any recommendations about which brand of AC's I should target?

92
Abhishek Jain (Mod)

Hi Rajarshi,

My room's dimension is 10*13 (roof exposed to sunlight) at south-east corner with two 3.5*4.5 window and two door; another room is 8.5*11 (also exposed) at south with with one 3.5*4.5 window and one door , for two peoples in each room at Burdwan,WB. Need to operate at night preferably (at weekend day time). ACs will be used for 4 months 5-6 hrs at summer time. Please suggest ACs with model no. and good service at Burdwan around 25-35k. Is Blue star multi-inverter AC will be useful?

96
Abhishek Jain (Mod)

Hi Chiranjit,
Your bigger room requires a cooling of 1.1 tons during night. And about 1.4 tons of cooling during peak summer daytime. Your smaller room requires cooling of 0.8 tons during night, and 1 tons of cooling during daytime.
Bluestar is a good brand but its 1 ton inverter AC is not highly efficient. For your usage you can go for BEE 5star AC. But at your budget you can go for 1/1.1 ton inverter ACs for both your room, an inverter AC is about 30% more energy efficient compared to BEE 5star AC, and it will also be able to cool your room during daytime in the weekends.

You can look at these 1/1.1 ton inverter ACs within 35k:

Dear BB team,
1st of all, thanking for sucha an useful information and research!! Appreciate this.
I am living almost close (newly built) area of Ahmedabad, doing night shift. I am looking for a split type of AC, most of the use of it during day time as we r doing night shift.
My house is an individual two storey small building. My bedroom is on 1st (top) floor, on the terrace we have tiles but guessing most of the heat effecting from the back and front rather than top. Temprature remains high (almost 45) during summer. My room size is just small (9X8 feet) one single glazed window! Enters sunlight till 11am. And we r only two in the room.
Can you suggest us a proper split type of AC according to our room, less energy consuming, less noise making(as the area is very very peaceful)
Auto temp. maintaining (auto on-off while sleeping mode).
Budget is 25-30K.
Really appreciate once again for the time and research.
A big thank

in furtherance to my query will u please suggest which ac is better out of o general,mitsubishi,diakin or hitachi & whether there is difference between indian manufactured piece & lmported one.Also whether inverter ac gives lower energy efficiency after some time of use say one year or it is amenable to more repairs as compared to normal split a.c

106
Abhishek Jain (Mod)

Hello Mr Jain,

The list we gave you is arranged based on energy efficiency. General, Mitsubishi, Daikin and Hitachi are all top brands and all of them have their own postives and negatives (you can choose the model as per the list we provided based on your budget and brand choice). In general imported ones are considered better although we do not think that India made are bad. There is no proof that inverter ACs give lower efficiency after one year. If you maintain it regularly (get regular cleaning done) then there is no reason for it to significantly decrease in efficiency. Normal derating happens for every AC (top brands have lesser derating). Maintenance is a bit more expensive for inverter AC (AMC for my 0.75 ton inverter AC costed me Rs 500 more per year than regular AC) however electricity savings far outweigh that. They are not amenable to more repairs but spare parts are expensive (it is important to protect them from power surges if they happen in your area). We have been suggesting inverter ACs to people for 3 years now and we have not heard any such complaints other than hearing people telling us stories about dealers suggesting them not to go for inverter AC as parts are expensive.

107

we have two separate rooms with 10*12 (roof exposed to sunlight) and 10*10 (not exposed) for two peoples each at Burdwan,WB. Need to operate at night preferably (seldom at peak times). Please suggest ACs with model no. and good service at my place.

108
Abhishek Jain (Mod)

Hi Siddarth,
According to our calculation your first room(10*12) requires a cooling of 1 tons during night time and 1.3 tons during daytime. And your second room(10*10) requires a cooling of 0.9 tons. Since your usage is mostly at night you can go for 1 ton ACs for both your room.
The type of AC required for your room will depend on your usage and budget. What is your usage of ACs in hrs/yr (separately)? And your budget for two ACs?

109

ACs will be used as minimum as possible and it may be about 90 days during summer at 4-5 hr/day. My budget is near about 30-35k each.

110
Abhishek Jain (Mod)

Hi Siddarth,
Your usage is low so we recommend you to go for BEE 3star 1 ton AC.

116
Abhishek Jain (Mod)

Hi Santosh,
According to our calculation your room two 100sqft room requires 1 tons of cooling. And 150sqft room requires 1.5 tons of cooling. We generally do not recommend people to go for window ACs as there are very few efficient models in window AC. You can go for a 1/1.1 ton inverter or a BEE 5star 1 ton AC for your two 100sqft rooms. And a 1.5 ton inverter or a BEE 5star 1.5 ton AC for your 150sqft hall.
Whether you go for an inverter AC or a BEE 5star AC depends on your usage. If your usage of AC is greater than 1200hrs/yr we recommend you to go for an inverter AC. If it is less than 1200hrs/yr you can go for a BEE 5star AC.

Dear Sir,
I am thankful to you for providing valuable information regarding every field to us, Sir I wanted to know which company is best in Manufacturing A/c, Mitshubishi Electric (ME) or Mitshubishi Heavy Duty (MHD)? What is the difference between them ? Some seller say that ME is assembled in India, some say MHD is imported totally from Japan etc,., And even wanted to know whether Air conditioner with heat pump is successful in Ahmedabad,Gujarat. As I am planing to buy such A/c but some seller are advising me not to buy such combo a/c as they are not successful in Ahmedabad.

Hi Ridham,

There is nothing like best brand in ACs. Everyone has some good things and some bad things. Between Mitsubishi Electric (ME) and Mitsubishi Heavy Industries (MHI) the general perception is that MHI is better as it is mostly imported. However MHI is not a widespread brand and if you are in a small place, getting service might get difficult.

A heat pump based AC would be good for you if you have a requirement of using room heaters in winters. I do not think Ahmedabad gets that cold that you need a room heater. Heat pump is 3-4 time more efficient than regular room heater. But I doubt you would be needing it in Ahmedabad. So it is not of much use to you. It will be better if you go for regular AC.
